testing of disinfecting efficacy of biocides


Chemila, spol. s r.o. is the laboratory accredited by CAI with the introduced system of Good Laboratory Practice.  Laboratory offers the testing of the declared disinfecting efficacy of chemical disinfectants and antiseptics using the actual EU standards.


For the basic orientation we recommend the standard EN 14885:2015. This standard presents the overview of currently valid standards for testing of chemical disinfectants and antiseptics. Thanks to the tabular reports it can be easily read the usability of individual standards with respect to the disinfectants area of use (medical, institutional, veterinary, industry ...), the intended use (disinfection of surfaces, tools, textiles ...) and the test organism (bacteria, mycobacteria, viruses, fungi and yeasts, algae). In another tables are also the mandatory testing conditions (time, temperature and interfering substances) according to the relevant standards listed.


The most current list of valid standards for testing of chemical disinfectants and antiseptics can be found on following pages: CEN/TC216.


Information on Biocidal Products Regulation (Regulation (EU) 528/2012)) is at disposal on  ECHA, information concerning the assessment and evaluation of biocides according PT categories is accessible in the form of Guidance on the BPR: Volume II Efficacy, Assessment + Evaluation (Parts B+C) [bpr_guidance_assessment_evaluation_part_vol_ii_part_bc_en.pdf].

Summary of information on product types, area and use of disinfectant and recommended standards for laboratory testing is at disposal here: ECHA_product types summary.xlsx


In addition to the standards mentioned in EN 14885:2015, we also offer other special tests specifying, for example, the efficacy of biocides against biofilm, efficacy of antimicrobial preservation of various materials (plastics, textiles, paints), determination of biocidal properties of wood preservatives and many others according to available European and international legislation.


We also determine the MIC (minimum inhibitory concentration) of biocides. MIC is the lowest concentration of an antimicrobial, that will inhibit, under particular test conditions, the visible growth of a microorganism after overnight incubation (bacteriostatic activity).
